"Gupta filed a complaint with the Sector 4 police post here and alleged that an unknown caller threatened to eliminate him. We are examining the complaint," Singh said, adding that he has been provided security.

Gupta married Honeypreet in 1999 and filed for a divorce in 2011.

Addressing a news conference in Chandigarh last week, Gupta had expressed apprehension that that he might be killed for speaking against the Dera head.

Honeypreet, against whom the Haryana Police had issued a lookout notice last month in connection with the violence in Panchkula, has been absconding since Dera chief Gurmeet Ram Rahim Singh's conviction on 25 August.
